Sub-Zero Professional Refrigeration Dual Installation with Classic (BI) or Designer (IT, IC, IW) Series


  • When installing Professional Refrigeration Series product next to a Classic (BI) or Designer (IT, IC, IW) Series Sub-Zero, which dual installation heater kit should be used?
  • Can a PRO3650 be installed next to a BI product
  • Can a Designer Wine Storage (IW) product be installed alongside a PRO3650 model?


When installing two different series next to one another, like a PRO3650 and a Classic (BI), Designer (IT, IC), or Designer Wine Storage (IW) model, and you do not have the minimum 2" filler, use the heater from either dual installation kit.

Refer to the Sub-Zero Design Guide for design specifications.
